다기능 복합 솔라윈도우 시스템의 채광 성능 평가

According to the recent report, the lighting energy consumption of commercial buildings reaches to 30%~40% of the total energy consumption. It is more than that of cooling & heating energy consumption and it is the major target of energy-saving policy. It is obvious that they are interested in natural lighting device such as Light-shelf for the purpose of raising the lighting energy-saving efficiency. The aim of this study was to analysis the Daylighting performance of Solar Window System built in apartments. the solar window is the idea to integrate daylight as a third form of solar energy into a PV/Solar Collector system. The process of this study is as follows: 1) Solar Window system are designed through the investigation of previous paper and work. 2) The simulation program(Lightscape3.2) was used in daylighting performance analysis. the reference model of simulation was made up to analysis daylighting performance on Solar Window system. 3) the simulation model for lighting performance analysis, lighting performance simulation with various variants, such as the size and installed area of Solar Window system.
